Seeping past waste tank valves

The last two trips out with our 2020 f28rks we've had the surprise of water waiting behind the cap. I'm good about having hose ready and catch this but have never had this issue with either previous RV. I'm assuming that the valves may be somewhat adjustable but that the belly cover would need opened. This last dump stop and both the front and galley connections had this problem. Anything I can do to remedy this, and I'm not wanting to add another shutoff to these, but to get the valves to function as they should.

In my coach valve it has a sliding white plastic guillotine blade that shut the flow off. If "something" gets stuck in the rubber seal where the guillotine slides water may leak. I occasionally will smear some Plumbers Grease on the blade. That not only seals the valve, but also makes it slide much easier.

Iíve had a similar problem that was caused by a small amount of plumbing pipe adhesive stuck in the groove that the valve slides in. Used some picks to clean it out. Solved the problem.

….some valves aren't accessible from the dump opening....for many valves, you can remove the 4 bolts on the coupling and remove the blade mechanism...."debris" trapped in the blade rubber seals is often the issue.....

If you do remove the valve, make sure you place something on the O ring that will hold it in place when trying to slide the valve back. That sucker can be a pesky rascal to keep the O rings from coming off.

When we first brought this coach home it too had a leaking valve. I ended up removing the valve so I could replace it. When I was inspecting it I found a very small hearing aid battery jammed in the rubber gasket. I removed the hearing aid battery, tested it (it was deader than a doornail) and after lightly coating the rubber gasket with the Plumber Grease put the valve back in. After 5 years its still working.

I spoke with dealer today and learned that are are no adjustments. The suggestion was to completely drain all tanks, then add clean water and see which valve may be seeping. I could then try flushing that out but if it doesnt clear any debris, the valve would have to be accessed for repair/replace, which would be a warranty claim.

Get some red dye and pour a bottle in one of the tanks. If the water collecting in the end cap os clear, you will know it is the other valve.

So, update. Grey tanks seem to be holding. Drained every drop out, put five gallons into them, no seepage. No surprise, the trouble is black tank valve. Will test to see if any debris has been rinsed out. The dealer described the repair process, nothing I want to take on, but not a big thing for the experts.
Next, to figure out why the main awning doesn't fully retract on the rear arm, but stays out about two inches. Photos sent to dealer.
Thanks to all who offered suggestions.

Iíve had similar problems and purchased a valterra valve that goes on where you attach your sewer hose. It acts as a safety in the event there is seepage past one of the tank valves. Once I have the hose connected to the trailer and into the drain then I open the valve before opening the waste valve on the tank. If they are leaking you will be able to see it if you have a clear elbow at either end and you wonít get any surprises taking the cap off.

X2 on the exterior Valterra waste valve. Itís a great safety feature and cheap too. Make sure you put some sort of safety strap (wire ties) on it because they will fall off.

I have the same problem with my black tank and don't want to tear into the valve so I use the Valterra valve on the end. With regards to your awning. Mine did the same. The awning sits in a channel on the top of the rig. There should be a small screw going through the top of the channel into the part of the awning that feeds into the channel. I had to remove the screw and slide the awning at the top towards the back a few inches. Then I reset the screw. That kept my awning from sliding and the arms back into their slots.

This twist-on valve is the best $20 investment I've ever made. Actually $80, I've had one on 4 different rigs!

We have added the Valterra valve at the end of the line like others. Glad we did. Makes life easier and less worry.

On the Glacier Peak, the valves are 3 feet from the handles....very hard to open and close due to the cable length. The only time I've had issues with seepage was debris caught in the valve.....drained the tank and put hot water in it. That did the trick.

You're under warranty....let them crawl under and remove the coroplast and deal with it.

Use the flush system every time you can.

I have not had the problem, but added the Valtera valve for insurance. I lube my valves by using some vegetable oil in the tanks, The black tank gets it added between draining and flushing. While flushing I operate the handle several times to "work" the vegetable oil into the seals. Worked so far.
